Should a scooter use 95 or 92 gasoline?

[VanOwen]

Scooter motorcycles should use 92-octane gasoline. Here are the specific details about gasoline: 1. Different anti-knock properties: 92-octane gasoline has relatively poorer anti-knock properties, requiring the ignition timing to be delayed, which leads to faster fuel consumption. In contrast, 95-octane gasoline's stronger anti-knock properties result in slower fuel consumption. 2. Different prices: In terms of price, 92-octane gasoline is slightly cheaper than 95-octane gasoline. 3. Different octane ratings: 92-octane gasoline consists of 92% isooctane and 8% n-heptane, making it suitable for mid-range vehicles. 95-octane gasoline contains 95% isooctane and 3% n-heptane, making it suitable for high-end vehicles.

I've been riding a scooter for over three years and always use 92-octane gasoline. The manual clearly recommends 92-octane because scooter engines typically have a compression ratio around 9 to 10, which doesn't require higher octane fuel. 95-octane is more expensive, and I've tried it without noticing any acceleration improvement. Sticking with 92-octane saves a lot of money in the long run, with fuel consumption consistently around 3 liters per 100 kilometers. Moreover, using higher-octane fuel with a mismatched compression ratio can lead to incomplete combustion and increased carbon buildup. Regular oil changes and air filter cleaning are far more important. In short, follow the manual and avoid unnecessary experiments.

To save money, just go with 92 octane. 95 octane costs a few cents more per liter, but for scooters, 92 is perfectly adequate as their engine design doesn't require high octane. Both my scooters run on 92, and I've tried 95 with no difference in power or fuel efficiency. In the long run, the savings could cover a new chain. Always follow the manual and don't overthink it.

92 octane gasoline is most suitable for scooters, as engines with low compression ratios may experience incomplete combustion when using higher-grade 95 octane. This isn't professional terminology but a simple matching issue. Trust the manual's recommendation to avoid carbon deposit risks.
